The sum of the 3 inside angles of a triangle need to equal 180.
Y = 180 - 90 - 48 = 42 degrees.

Answer:
-17x-3
Step-by-step explanation:
Distribute the negative to the second part of the equation. remove the parenthesis from the first part and then add like values.
-4x-2-13x-1
-4x-13x-2-1
-17x-3
Step-by-step explanation:
line s || line t
r is the transversal,
Therefore,
(7x-2)°= (6x+18)° {exterior alternate angles}
7x-6x=18+2
x=20°
r is also a straight line,
therefore,
7x-2+angle1=180° (straight angle)
7x-2+ angle1=180°
7(20)-2+ angle 1= 180°
140°-2+ angle 1= 180°
angle 1= (180-140+2 )°= 42°
angle 1= 42°
(5x-12)^2
Square factor of 25 is 5.
Square factor of 144 is 12.
Hope this helps. I didn't understand what to do with it.
